Builder’s risk insurance is a standard component of most construction project programs, and the policy form that works well for a traditional design-bid-build project may benefit from review when the delivery method is design-build.
The distinction matters because design-build projects create exposures that standard builder’s risk forms were not written to address. Understanding where those considerations arise is useful for any design-build firm that wants to confirm its project insurance program is appropriately structured before work begins.
What Standard Builder’s Risk Covers
A standard builder’s risk policy covers the physical project under construction against direct physical loss or damage from covered causes, which typically include fire, wind, lightning, theft, vandalism, and accidental damage during the construction process. Coverage attaches when physical construction begins and terminates at project completion, occupancy, or policy expiration.
The policy insures the value of the work in place, including materials stored on site and, in many forms, materials in transit to the project. Most policies also include coverage for the cost of demolition and debris removal following a covered loss.
Standard builder’s risk was designed around a project delivery model in which the design is substantially complete before construction begins. The contractor builds from finalized plans, and the risk the builder’s risk policy addresses is primarily physical — what happens to the structure and materials while they are being assembled.

How Design-Build Changes the Coverage Equation
In a design-build delivery, the design and construction processes overlap. The design-build contractor begins performing design work before any physical construction starts, and design development continues in parallel with early construction phases on many projects. This creates a pre-construction design phase during which costs are accumulating and contractual commitments are being made, but no physical construction exists to trigger coverage under a standard builder’s risk form.
Standard builder’s risk policies also include professional liability exclusions, which remove coverage for losses arising from design errors, omissions, or professional negligence. In a traditional design-bid-build project, this exclusion does not create a significant gap for the contractor because the contractor is not responsible for the design. In a design-build project, where the contractor holds both the design and construction obligations, the professional liability exclusion in the builder’s risk form intersects with the contractor’s own professional liability exposure in ways that deserve careful attention.
According to the Design-Build Institute of America, design-build delivery now accounts for more than 44 percent of US construction volume across commercial, institutional, and infrastructure sectors. As design-build has grown as a delivery method, the insurance market has developed coverage options specifically structured for the design-build environment, including policy forms that address the pre-construction phase, modified delay in completion coverage, and more explicit treatment of professional liability exposure in the context of builder’s risk.
The question of who provides the builder’s risk policy on a design-build project, whether the project owner or the design-build contractor, is determined by the contract and should be confirmed before the project begins. The contract should clearly specify who is responsible for obtaining the policy, what coverage limits apply, who is named as an insured, and how the builder’s risk policy interacts with the separate professional liability coverage carried by the design-build contractor.

What to Review in Your Design-Build Builder’s Risk Program
A design-build firm reviewing its project insurance program should confirm several specific items.
Coverage for the pre-construction design phase should be addressed in the program structure, whether through a soft costs endorsement, a design-build specific policy form, or another mechanism. The interaction between the builder’s risk form and the firm’s professional liability policy should be reviewed to confirm that the professional liability exclusion in the builder’s risk form does not leave a gap for design-related losses.
Delay in completion coverage, which addresses the financial costs of project delays, should be reviewed specifically for how design-caused delays are treated. An exclusion for delays attributable to design errors can create gaps on design-build projects that would not exist on a traditionally delivered project of comparable scope and value.
Subcontractor coverage is another consideration. Whether subcontractor work is covered under the design-build contractor’s builder’s risk program, or whether subcontractors are required to obtain their own coverage for their scope, should be clearly addressed in both the policy and the contract with each subcontractor.
Reviewing specialty programs available to design-build contractors alongside the commercial insurance program is a practical starting point for confirming that the project insurance structure is appropriate for the delivery method your firm uses.
